Like many others who have posted here, I have found this program to be a complete and utter rip off...they want you to pay and pay and pay, even if they're not sending you ink cartridges because you're not using the 'monitored' ink, for whatever reason. If you stop paying the monthly fee, even though you have full ink cartridges THAT YOU HAVE ALREADY PAID FOR, THEY WILL SHUT OFF THE INK CARTRIDGES WITH THE EMBEDDED CHIP AND HOLD YOUR REMAINING INK HOSTAGE.
And their customer service is beyond disappointing. I WILL NEVER PURCHASE ANOTHER HP PRODUCT AFTER MY EXPERIENCE WITH THIS PROGRAM AND IT'S CUSTOMER SERVICE REPS.
I signed up for a free promotion for this program when I purchased my new printer. I've had internet connectivity issues with the printer and have only used the printer a handful of times over the 6mths I've had it. I haven't even needed to insert the brand new, still wrapped replacement ink cartridges that they have already sent me.
I changed credit cards and failed to update my new credit card info on their website, so they did not receive the monthly payment for their Sept 3rd-Oct 2nd billing period (it is currently Sept 21st) I wasn't in any rush to update my info because I was considering that there didn't seem to be any value for me with this program.
I discovered when I went to print a page, for the first time in a month and half, that my printer no longer works, and displays a message saying to contact HPink.Com. Upon calling their customer service line, I was told that unless I kept paying the monthly fee, they will not turn my ink back on, and I cannot use any of the ink that I already have, AND EVEN THOUGH THEY HAVEN'T SENT ME INK IN MONTHS. I currently have 3 unopened, unused ink cartridges that were sent to me previously, and a full black cartridge that I had just opened, that are completely useless to me.
AVOID THIS PROGRAM LIKE THE PLAGUE...unless you are able to print right to their limit every month (don't go over or they'll charge you even more!), or you don't mind paying regularly for nothing...
